With just 10 minutes a day, users can listen to and repeat 100 sentences provided by the app. The app offers a daily average of 150 or more cash rewards, making it an attractive option for those looking to earn while learning.

One of the standout features of 스픽볼 is its support for Korean pronunciation. For users who find it difficult to follow along or struggle with certain sentence pronunciations, the app provides support by displaying the Korean pronunciation alongside the English sentences.

Repetition is key to effective learning, and 스픽볼 understands this. The app supports up to 5 repetitions per sentence, allowing users to reinforce their understanding and pronunciation.
